ELECTRIC SWITCH.

- SPECIFICATION forming part of Letters Patent No. 605,067, dated June '7, 189s.

l A Application tiled September 17, 1897. Serial No. 651,983. (No model.)

To af/ZL whom it may concern:

, Beit-known that LCH-ARLES' C. BADEAU, a citizen'of the United States, residing at Schenectad y,in the county of Schenectadyand'State of NewYork, have invent-ed a certainl new and useful Improvement in Electric Switches, ofwhich thevfollowingnis a specification.

t The object of my invention is to Aproduce a cheap and strong form of switch, one in which the parts are readily attached to a large switchboard, such as are now commonly-.in use in electric-lighting plants.l

My invention is illustrated in the accompanying drawings, in which- Figure 1 is a side elevation, and Fig. 2 a

form. i

*Referring tothedrawings, and more particularly ltoFigs, lljand 2, A represents a switchboard, which is usually vmade of slate or marble, the switch members comprising a standard B, to whichthe movable switchblades are pivoted, and'a stationary contactplatcsB and B2. v f

C are the movable switch-blades.

'I he standard B and contact-plates AB and B2 are cut from heavy strip metal and bent into L shape, and these parts are passed upward through the switchboard A, the opening for these parts being made by drilling a series of holes, as indicated in dotted lines at the left of Fig. 2.

D D are top plates provided with a slot through which the standard B and contactplates Bf and B? arepassed, and these plates are intended to cover the holes drilled in the switchboard A.V The standard B and contact-plates are held in position by bolts E,

the two ends of the switch-blade a spacingblock C of the same thickness as the parts B, B', and B2 is-rmly riveted in position.

In'thczdrawings I have illustrated in Figs. l and-'2 a double-pole ,double-throw switch, and Fig. 2 shows the two switch-blades connected together by a yoke F, ofk insulating material, to'Awhich-thc operating-handle G is.

secured. l

In Fig. 3 the standard B and contact-plate B"`are of the same form as those shown in Figs. l and 2, but instead of being passed through the switchboard A they are bolted to the front of the board bybolts passing through theswitchboard 'and screwing into the parts b." The heads :of'the bolts are pref- .erably countersunk in the back 'of theswitchboard."` These bolts are also provided Ywith nuts e, as in Fig. l, for clamping the circuitterminals to the switch members.

With my improved form of switch no cast parts are employed and all machine-work is obviated, the various .parts ,being cut from smothstrip`v metal of; uniform'kwidtn and thickness, vand hence requiringV no finishing except the bending and Y'(:l'rilling of holes. The parts are few and simple in construction, arereadily and cheaply made, and can be quickly assembled on a switchboard. Furthermore, my improved form of switch-blade is well adapted for double-throw swithces.

-What I claim isl. In an electric switch, the combination of a switchboard, stationary switch members secured to said board, a pivoted switch-blade cooperating with said switch members and made from a strip of metal bent lengthwise upon itself, and of substantially uniform .width throughout, and a handle secured to the switch-blade at the bend, substantially as herein specified.

2. In an electric switch, the combination of a switchboard, stationary switch members bent into L shape and passed through holes in the switchboard and held in position by bolts screwed into the parts of the switch members underneath the switchboard, the bolts being provided with nuts for clamping circuit-terminal sto the parts ofA theswitch members underneath the switchbgardha pivoted switch-blade made 'from a strip ofvmhetal IOO bent lengthwise upon itself, and a handle secured to the switch-blade at the bend, substantially as herein speciiied.

3. In an electric switch, the combination of a switchboard, stationary switch members bent into L shape and passed through holes in the switchboard and held in position by bolts screwed into the parts of the switch members underneath the switchboard, the bolts being provided with nuts for clamping circuit-terminals to the parts of the switch members underneath the switchboard, a pivoted switch-blade made from a strip of metal bent lengthwise upon itself, and having a loop formed at the bend, and a handle secured to the switch-blade at the bend, substantially as herein speciied.

l. ln an electric switch, the combination of a switchboard, stationary switch members bent into L shape and passed through holes in the switchboard and held in position by bolts screwed into the parts of the switch members underneath the switchboard, the bolts being provided with nuts for clamping circuit-terminals to the parts of the switch members underneath the switchboard, a pivoted switch-blade made from a strip of metal bent lengthwise upon itself, and having a loop formed at the bend, a spacing-block between the switch-blade, and a handle secured at the bend, substantiallyT as herein described.

5. In an electric switch, the combination of.' a switchboard, L-shaped stationary switch members passed through a slot in the switchboard formed by drilling a series of holes, a slotted covering-plate for each stationary switch member for covering said holes and which plates are provided with bolt-holes, bolts passing through said plates and the switchboard and screwed into the parts of the stationary switch members underneath the board whereby said members and the covering-plates are secured to the board, and a pivoted switch-blade made from a strip of metal bent lengthwise upon itself, the two ends being pivoted to one of the stationary switch members, and having a handle secured to it at the bend, substantially as herein specified. This specification signed and witnessed this ith day of September, 1807.
